dc.description.abstractEffect of carbon, nickel and copper on the wear resistance of Fe-xNi-yC-zCu (x=14 to 20 wt. %, y= 0.6 to 1.0 wt. % and 0 to 8 wt. %) fully austenitic alloys was investigated in the view point of strain energy for initiating the martensitic transformation. The strain energy and hardness increased with increasing carbon, nickel and copper concentration. Unexpectedly, the wear resistance decreased in spite of the increasing of hardness. It was considered to be due to that the increment of energy needed for initiating the martensitic transformation made it hard to transform austenite into martensite with increasing carbon, nickel and copper concentration. In this study, strain-induced martensitic transformation was thought to be more important factor to increase wear resistance than hardness.; Carbon, Nickel 그리고 Copper의 첨가가 Fe-xNi-yC-zCu (x=14~20 wt. %, y= 0.6~1.0 wt. % and 0~8 wt. %) 의 오스테나이트 합금의 마모저항성에 미치는 영향에 대해서 변형유기상변태가 일어나는데 필요한 에너지의 관점을 통해 고찰하였다. Carbon, Nickel, Copper 첨가량이 감소함에 따라 변형유기상변태가 일어나는데 필요한 에너지와 합금의 경도는 낮아지는 것으로 나타났다. 하지만, Carbon, Nickel, Copper의 첨가량이 낮음으로 인해 경도가 낮음에도 불구하고 합금의 마모저항성은 증가하였음을 알 수 있었다. 이는 Carbon, Nickel, Copper 첨가량의 감소에 따라 변형유기상변태가 일어나는데 필요한 에너지가 낮아짐으로 마모과정에서 변형유기상변태가 잘 일어남에 따른 결과로 생각된다.-
