Heat treatment conditions are characterized by the following parameters: heating temperature t max , i.e.the maximum temperature to which an alloy metal is heated; time of holding at the heating temperature ; heating rate and cooling rate .如果以不变速率加热或冷却，则温度和时间的关系可以具有不同...
The objective of this section is to begin with a generalized discussion of the constitution of commercially pure iron, subsequently leading to discussion of the ironcarbon alloy system that is the basis for all steels and their heat treatment. All pure metals, as well as alloys, have individual...
