Regular spherical chromium doped spinel lithium manganese oxides (LiCr_(0.04)Mn_(1.96)O_4) with an average particle size of about 20 μm were prepared by the sl
AB5 (MINi_(4.0)Al_(0.3)Cu_(0.5)Zn_(0.2)) alloy and CoB alloy were prepared by arc melting. AB_5-CoB composites were synthesized by simple mixing of AB_5 alloy p
The dendrite morphologies and spacings of directionally solidified DZ125 superalloy were investigated under high thermal gradient about 500 K/cm. The results re
