The effect of heat treatment on microstructure and microhardness of directionally solidified(DS)NiAl-Cr(Mo)-Hf alloy is investigated. The results indicate that
A coating with high hardness, wear and oxidation resistance was prepared by electric arc spray. The hardness,bonding strength, abrasive wear and values of poros
The present study was carried out to illustrate high-efficient detection of quantitative trait loci(QTLs)with selected introgression lines(ILs)and the existence
