  • Alloys: Making an Alloy
    Inspirational chemistry 21 Alloys: making an alloy Index 2.3.1 2 sheets In this experiment, students make an alloy (solder) from tin and lead and compare its properties to those of pure lead. Equipment required Per pair or group of students: ■ About 2 g lead ■ About 2 g tin ■ Crucible ■ Pipe clay triangle ■ Bunsen, tripod and heatproof mat ■ Spatula ■ Carbon powder – 1 spatula per student ■ Tongs ■ 2 sand trays or sturdy metal lids ■ Sand ■ Access to a balance ■ Eye protection. Health and safety The most likely incident in this experiment is a student burning themselves so warn them that the equipment will be hot. Pouring molten metal can be hazardous if you are not sure how to use tongs correctly – it would be worth demonstrating how to use them safely. Some tongs in schools do not grip well. Every pair must be checked before the start of the experiment. Eye protection should be worn. Lead is a toxic metal. If it is heated for too long or too high above its melting point it could start to give off fumes. Ensure that the laboratory is well ventilated, warn students against breathing in the fumes given off by their sample during the experiment and tell them to heat the metals no longer than is necessary to get them to melt. 22 Inspirational chemistry Results Hardness testing should show clearly that the alloy is harder than the pure lead. The alloy can be used to scratch the lead convincingly. The lead does not leave a mark on the alloy. (Students may need to be reminded how to do this simple test – just try to scratch one metal with the other.) The density of the alloy should be less than that of the lead, but this test is fairly subjective.

  • Definition of Design Allowables for Aerospace Metallic Materials
    Definition of Design Allowables for Aerospace Metallic Materials AeroMat Presentation 2007 Jana Jackson Design Allowables for Aerospace Industry • Design for aerospace metallic structures must be approved by FAA certifier • FAA accepts "A-Basis" and "B-Basis" values published in MIL-HDBK-5, and now MMPDS (Metallic Materials Properties Development and Standardization) as meeting the regulations of FAR 25.613. OR • The designer must have sufficient data to verify the design allowables used. Design Allowables for Aerospace Industry • The FAA views the MMPDS handbook as a vital tool for aircraft certification and continued airworthiness activities. • Without the handbook, FAA review and approval of applicant submittals becomes more difficult, more costly and less consistent. • There could be multiple data submission for the same material that are conflicting or other instances that would require time consuming analysis and adjudication by the FAA. What is meant by A-Basis, B-Basis ? S = Specification Minimum • B-Basis: At least 90% of population A = T equals or exceeds value with 95% 99 confidence. B = T90 • A-Basis: At least 99% of population equals or exceeds value with 95% confidence or the specification minimum when it is lower. Æ Mechanical Property (i.e., FTY, et al) What is the MMPDS Handbook? • Metallic Materials Properties Development and Standardization • Origination: ANC-5 in 1937 (prepared by Army- Navy-Commerce Committee on Aircraft Requirements) • In 1946 the United States Air Force sanctioned the creation of a database to include physical and mechanical properties of aerospace materials. • This database was created in 1958 and dubbed Military Handbook-5 (or MIL-HDBK-5 for short).

  • Chapter 18 Solutions and Their Behavior
    Chapter 18 Solutions and Their Behavior 18.1 Properties of Solutions Lesson Objectives The student will: • define a solution. • describe the composition of solutions. • define the terms solute and solvent. • identify the solute and solvent in a solution. • describe the different types of solutions and give examples of each type. • define colloids and suspensions. • explain the differences among solutions, colloids, and suspensions. • list some common examples of colloids. Vocabulary • colloid • solute • solution • solvent • suspension • Tyndall effect Introduction In this chapter, we begin our study of solution chemistry. We all might think that we know what a solution is, listing a drink like tea or soda as an example of a solution. What you might not have realized, however, is that the air or alloys such as brass are all classified as solutions. Why are these classified as solutions? Why wouldn’t milk be classified as a true solution? To answer these questions, we have to learn some specific properties of solutions. Let’s begin with the definition of a solution and look at some of the different types of solutions. www.ck12.org 394 E-Book Page 402 Homogeneous Mixtures A solution is a homogeneous mixture of substances (the prefix “homo-” means “same”), meaning that the properties are the same throughout the solution. Take, for example, the vinegar that is used in cooking. Vinegar is approximately 5% acetic acid in water. This means that every teaspoon of vinegar contains 5% acetic acid and 95% water. When a solution is said to have uniform properties, the definition is referring to properties at the particle level.

  • Evolution of the Eutectic Microstructure in Chemically Modified and Unmodified Aluminum Silicon Alloys
    Evolution of the Eutectic Microstructure in Chemically Modified and Unmodified Aluminum Silicon Alloys by Hema V. Guthy A Thesis Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Master of Science in Materials Science and Engineering April 2002 APPROVED: _____________________________________________ Prof. Makhlouf. M. Makhlouf, Major Advisor _____________________________________________ Prof. Richard D. Sisson, Jr Materials Science and Engineering Group Head i ABSTRACT Aluminum-silicon alloys are an important class of commercial non-ferrous alloys having wide ranging applications in the automotive and aerospace industries. Typical aluminum-silicon alloys have two major microstructural components, namely primary aluminum and an aluminum-silicon eutectic. While nucleation and growth of the primary aluminum in the form of dendrites have been well understood, the understanding of the evolution of the Al-Si eutectic is still incomplete. The microstructural changes caused by the addition of strontium to these alloys are another important phenomenon that still puzzles the scientific community. In this thesis, an effort has been made to understand the evolution of the Al-Si eutectic in the presence and absence of strontium through two sets of experiments: (1) Quench experiments, and (2) sessile drop experiments. The quench experiments were designed to freeze the evolution of the eutectic after various time intervals along the eutectic plateau. The sessile drop experiments were designed to study the role of surface energy in the formation of the eutectic in the presence and absence of strontium. Both experiments were conducted on high purity alloys. Using observations from these experiments, possible mechanism(s) for the evolution of the Al-Si eutectic and the effects of strontium on modifying the eutectic morphology are proposed.

This work aimed to improve the properties of FeAl20Si20 alloy (in wt.%) by the application of powder metallurgy process consisting of ultrahigh-energy mechanical alloying and spark plasma sintering. The material consisted of Fe3Si, FeSi, and Fe3Al2Si3 phases. It was found that the alloy exhibits an anomalous behaviour of yield strength and ultimate compressive strength around 500 ◦C, reaching approximately 1100 and 1500 MPa, respectively. The results also demonstrated exceptional wear resistance, oxidation resistance, and corrosion resistance in water-based electrolytes. The tested manufacturing process enabled the fracture toughness to be increased ca. 10 times compared to the cast alloy of the same composition. Due to its unique properties, the material could be applicable in the automotive industry for the manufacture of exhaust valves, for wear parts, and probably as a material for selected aggressive chemical environments.
