Different heat treatments are based on the subsequent cooling and reheating of the austenitized material. Phase diagrams are important tools for understanding the heat treatment process. Several different diagrams and charts can be derived from the basic all-encompassing diagram; some of which are ...
The chemistry and heat treatments of steel alloys are designed to eliminate any negative effects due to ductile–brittle transition and temper embrittlement. Fracture in these alloys occurs by the nucleation of voids at impurity particles, principally sulfides and oxides, and their subsequent coalescence...
It helps to relieve the internal stresses, and makes the steel less brittle than before. The properties of tempered steel enable us to use it in the manufacture of tools which need a fairly hard steel, but it is much more difficult to work. These heat treatments take place during the ...
Thermal Treatments range from quenching to long holds, 24 hours, at a fixed Temperature. In all cases the thermal processing controls the microstructure and so also The mechanical properties. Hardenability of a Steel Hardenability is the ability of a steel to form martensite. The greater the ...

After reviewing heat treating operations for steel and the principles of the heat treatment of steel, an overview of induction heat treating is provided. Next, consideration is given to equipment and equipment selection, coil design, power requirements and temperature control. A discussion of surface...
This paper presents the results of tribological tests performed on a T-11 pin-on-disc type, which made it possible to determine the intensity of abrasive wear of steel 20MnCr5 subjected to selected thermo-chemical heat treatments. The te... M Leola 被引量: 0发表: 2016年 (J36-1202)Surface...
