Google Scholar The 34CrNiMo6 steel is one kind of heat-treated low-alloy engineering steel with high strength and hardenability, which contains nickel, chromium, and molybdenum . Moreover, the 34CrNiMo6 steel also has good toughness properties at low temperature, which ensures the shock resistance of the material is good enough in the service temperature environment. Measurements of the shapes of the cyclic, stress-strain hysteresis loops obtained from AISI 1070 (HRC 60) and AISI 52100 (HRC 62) steels subjected to constant stress and constant plastic strain amplitude cycles in torsion are presented. The study examines plastic strain amplitudes in the range of 0.0002 ≤ Δεp/2≤ 0.0015, which are similar to the strain amplitudes produced by rolling contact.

Measurements of H1 Hardness It is reported that Crucible metallurgists measured H1 hardness and found it to be approximately 58 Rc at the … Each step of the heat treating cycle is designed to perform a specific function, and, like links in a chain, the final product is only as good as its weakest component. Although it may only represent 10% or less of the cost of the tool, the heat treat process is probably the single most important factor in determining the performance of a tool. AISI 1040 carbon steel can be welded using all welding techniques. It can be pre-heated at 149 to 260°C (300 to 500°F) and post-heated at 594 to 649°C (1100 to 1200°F) due to its high carbon content. Heat Treatment. AISI 1040 carbon steel can be heat treated at 844 to 899°C (1550 to 1650°F) followed by quenching in water and tempering. Preheating: Heat at a rate not exceeding 400°F per hour (222°C per hour). For complex and large tools, heat to 1150-1250°F (621-677°C) and equalize. Then heat to 1300-1400°F (704-760°C) and equalize. For simple geometries, use only the second preheating temperature range. The mechanical properties of steel will certainly change with heat treatment and microstructure but this statement pertains to the properties that are governed by plasticity, e.g., strength ... Steel is typically austenitized at 900–1000 °C before it is quenched and tempered. The high-frequency alternating magnetic field of induction heating heats the steel by two mechanisms below the Curie temperature: resistance or Joule (I 2 R) heating and ferromagnetic hysteresis losses.

It is somewhat common for knifemakers to heat treat low alloy steels in a forge or with a torch, two methods where tight temperature … 2.2. HEAT TREATMENT:- The process of heat treatment is carried out first by heating the material and then cooling it in the brine, water and oil. The purpose of heat treatment is to soften the metal, to change the grain size, to modify the structure of the material and to relieve the stress set up in the material after hot and cold working. Apr 03, 2014 · The cause of magnetostriction is revealed by analyzing this phenomenon in a polydomain crystal of Fe. It is based on the two fundamentals: (a) magnetization is a rearrangement of spin directions by rearrangement of the crystal structure, and (b) the α-Fe has a tetragonal rather than cubic structure. The magnetostriction results from bringing the shorter tetragonal axis to coincide with, or ...
