Effect Of Cooling Rate On Microstructures And Mechanical Properties Of C102 Copper Alloy

The objective of this study is to illustrate the effect of two types of heat treatment on microstructure and mechanical properties of C102 copper alloy. Annealing and quenching were conducted to study the effect of cooling rate on material. Specimens were heated at 350, 400 and 500oC and were coo...
