Tamirisakandala等报道了通过在Ti-6Al-4V合金中添加0.1%硼,使合金的β晶粒尺寸由1 700μm减小为200μm。然而截至目前,对于添加硼的Ti-6Al-4V合金在热机械加工过程中的变形行为和显微组织演化还不是很清楚。为此,印度学者ShibayanRoy等人对添加硼的Ti-6Al-4V合金进行了热压缩试验,研究了变形温度和应变速率对变形行为和组织 Tamirisakandala et al. Reported that by adding 0.1% boron to the Ti-6Al-4V alloy, the β crystal grain size of the alloy was reduced from 1 700 μm to 200 μm. However, so far, the deformation behavior and microstructure evolution of Ti-6Al-4V alloy added with boron during the thermomechanical processing are still not clear. To this end, Indian scholar Shibayan Roy et al on boron-added Ti-6Al-4V alloy was subjected to hot compression tests were studied deformation temperature and strain rate on the deformation behavior and organization
