strengthening effect
3.carbon equivalent(C_(eq)) influences the strengthening effect of A3 and 16Mn angle steels after controlled cooling, generally, the more carbon equivalent, the more strengthening effect;
4.In this experiment, it is increased by 19%~37%, indicating that domestic CFS has good property, low price and satisfactory strengthening effect.
5.The results of calculation illustrate that the contribution of T 1 phase is about 30%～60% to the total critical resolved shear stress (CRSS), and that the strengthening effects of T 1 phase in 2090 and 2090+minor Ce alloys are little different at under aged condition, but the strengthening effect of T 1 precipitates in alloy containing cerium is less bigger than that of 2090 not containing cerium under over aged condition, especially the cutting mechanism is only considered.
8.Influence of strengthening treatment on the deformation of Al 2O 3/SiO 2 nano-compound ceramic core at high temperature was examined. The results showed that the strengthening treatment has great effect on the deformation of Al 2O 3/SiO 2 nano-compound ceramic core at high temperature. The deflection of the ceramic core at 1 550 ℃ for 1 h dropped from 7 mm to 1 mm before and after being strengthened.
9.This article bases specifically on engineering geology condition of one cutting slope in Guangdong Shanmei highway, and adopts laboratory similarly model test to investigate and discuss the strengthening machanism of multi-bolts and its effect.
10.This paper analyzes on the loss brought about by the brain drain to the hospital,and points out that carrying out the labor contract management and strengthening the restraint of the labor contract possess certain effect on controlling and reducing the brain drain of the hospital.
