Review Onaluminium and Its Alloysfor Automotive Applications
REVIEW ONALUMINIUM AND ITS ALLOYSFOR AUTOMOTIVE APPLICATIONS Md.Tanwir Alam1, Akhter Husain Ansari2 Department of Mechanical Engineering, Aligarh, Muslim University, Aligarh-202002, India. ABSTRACT Aluminium has a density around one third that of steel or copper. It is one of the lightest commercially available metals in the markets. The resultant high strength to weight ratio makes it an important structural material. This allows an increased payloads or fuel savings for transport industries in particular. In the present scenario, a review of aluminium and its alloys have been made to consolidate some of the aspects of physical, mechanical and wear behavior. The importance of aluminium and its alloys as engineering materials is reflected by the fact that out of over 1600 engineering materials available in the market today more than 300 wrought aluminium alloys with 50 in common use. These materials initially replaced cast iron and bronze alloys but owing to their poor wear and seizure resistance.These materialswere reported by the number of researchers for the past 25 years. In the present study, based on the literature review, the aluminium and its alloys have been discussedin quite detail. Aluminium and its alloys are finding increased applications in aerospace, automobile, space shuttle, underwater, and transportation applications. This is mainly due to light weight, improved physical, mechanical and tribological properties like strong, stiff, abrasion and impact resistant, and is not easily corroded. Key words:Aluminium, Aluminium Alloys, Alloy Designations, Aluminium Technical Data I.INTRODUCTION The possibility of taking advantage of particular properties of the constituent materials to meet specific demands is the most important motivation for the development of any specific material. -

Mechanical Metalworking: from Manual to Computer-Based Processes
August 04, 2021 Mechanical metalworking: from manual to computer-based processes Just like in an ordinary kitchen, there is more to the steelmaker’s kitchen than just the processes where high temperature plays a crucial role, such as boiling, roasting or baking. Before a dish can be served, it needs additional work to make it more appealing. The same is true of metals. Prior to their use, plates, tubes, rods and complex steel castings are subject to cold forming by special metalworking machines and lathes, which become more and more sophisticated each year. History of mechanical metalworking Let’s look first into the history of mechanical metalworking and its origins. Unlike many other processes that are unique to steelmaking, some ideas related to the mechanical working of metal surfaces came from related areas. The ancient Egyptians had devices for drilling holes in stones. Wood machining equipment that later evolved into turning lathes existed in the sixth and seventh centuries BC. Yet these types of processes were not applied to metals for hundreds of years. For a long time, metal surface treatment had several restricting factors. First, it required harder tools. Second, small-batch production did not need high-precision metalworking. Third, the industrial revolution and mass production of uniform products only became a reality in the 18th-19th centuries. The third reason was a key prerequisite for the appearance of mechanical metalworking. Smiths that made goods for individual orders gave way to large industrial manufacturers and factories that had the capacity to produce large quantities of uniform metal goods. Gunsmiths were among the first to appreciate the importance of standardised metalworking. -

Electrochemical Surface Finishing Is a Highly Scalable
Electrochemical Surface Finishing by E. J. Taylor and M. Inman lectrochemical surface finishing is a highly scalable to enable uniform polishing. For example, hydrofluoric acid and/ manufacturing process that traditionally uses viscous, or fluoride salts are added to traditional electrolytes to depassivate non-aqueous and/or highly acidic electrolytes to achieve the surface for strongly passive metals such as niobium and Nitinol E 5 the desired surface profiles on metallic parts, with the addition of alloys. In addition to the electrolyte handling and safety issues aggressive, hazardous chemical species to remove the oxide film on associated with concentrated hydrofluoric acid, conventional DC strongly passive materials. An emerging approach applies pulse and electropolishing of these materials presents process control issues, pulse reverse electric fields to control current distribution, mitigate and reject rates can be as high as 40 to 50%.6 oxide film formation and achieve the desired surface finish, in the This reliance on chemical mediation can be traced back 150 presence of environmentally benign and simple chemistries.

Surface Finishes and Clean Ability
Surface Finishes and Clean ability The Design and Manufacture of Cleanable Equipment Specifying the appropriate material, manufacturing process and surface finishing method to economically meet your hygiene goals Paul Kennedy - Owner Pragmatics Engineering 3A CCE HOW TO SELECT A GRADE OF STAINLESS Stainless steels are engineering materials with good corrosion-resistance, strength and fabrication characteristics. They can readily meet a wide range of design criteria, including load, service life and low maintenance. Selecting the proper stainless steel grades involves weighing four qualities in the following order of importance: HOW TO SELECT A GRADE OF STAINLESS Corrosion or Heat Resistance the primary reason for specifying stainless. The specifier needs to know the nature of the environment and the degree of chemical / heat resistance required both during production and cleaning Mechanical Properties particularly strength at production and cleaning temperatures. The combination of corrosion resistance and strength is the basis for selection. Fabrication Operations how the product will be made e.g., forging, machining, forming, welding, stamping, roll forming etc. Total Cost include material and production costs and consider the cumulative savings of a long lived maintenance-free product. Chemical / Heat Resistance Type 304 stainless steel is versatile and wide ranging. It serves a variety of industrial, architectural, consumer, and transportation applications. It offers a high level of resistance to corrosion but will eventually show signs of tarnish over time. 304’s composition provides a better structural advantage and durability than other grades of stainless steel. For manufacturing purposes it’s customizable and easy to fabricate; making it the most widely used commercial stainless steel today. -
