摘　　要：着重研究了开坯轧制温度对钼板组织与性能的影响。试验表明，低温开坯轧制与高温开坯轧制相比，采用低温开坯轧制的钼板晶粒细长，晶界相互连锁搭接，强度及延伸率高。The effects of breakdown rolling temperature for molybdenum plate billet on the properties and microstructure of final product have been investigated. The results show that the grains obtained by low temperature breakdown rolling are much slimmer than that by high temperature one, and the boundaries by former process have much higher degree of chain over lapping. Both of the factors provide the final product by low temperature breakdown proccess with higher strength and elongation, thus better comprehensive properties as a whole.
