Three high-nitrogen stainless steels with different N contents were successfully processed by equal-channel angular pressing for one pass, and their microstructures and mechanical properties were investigated. It was found that the microstructure of the billet was heterogeneous across the billet thickness, resulting in the difference in the mechanical properties due to the different deformation conditions. A relatively low strength, high uniform elongation, and high work-hardening rate for the samples at the bottom of the billet was achieved in comparison with those processed at the top. Meanwhile, it was observed that the density of deformation twins increased with the content of N; accordingly, the strength and elongation of the alloys increase with the content of N, resulting in a good strength-ductility combination.

研究了F? P—N合金加?对Snoek—Ke-Koster(SKK)峰的影响,发现与合金含La,P的原子浓度比(C_(La)/C_p)有关:对于C_(La)/C_p较大(例如4.56和2.6)的合金,La有明显增强SKK阻?效应:对于C_(La)/C_p=0.27的P过饱和合金,La对SKK峰无明显影响。

Assuming that the wave function , the Schrodinger equation can be written as . Neglecting the last two terms, an analytical expression of electron dynamical diffraction was derived by Qibin YANG et al. In this paper, the analytical expression is modified by further considering the second-order differential term . When the accelerating voltage is not very high, or the sample is not very thin, the reciprocal vector ɡ is large, the modification of the second-order differential is necessary; otherwise it can be neglected.

The strong effect of rare earth(RE)on medium-temperature internal friction(IF)of commercially pure iron is closely related to the heat treatment.The RE added into iron has an alloying effect.The Snoek-Ke-Kster(briefly SKK)peak lower as the aging temperature in- creases from 150℃ to 450℃,but it still exists even aged at 600℃.However,the SKK peak temperature T_p does not simply falls as the ascending of aging temperature,it rises again at 600℃ aging.

Dynamic Monte Carlo simulation is used to explore the B isotope sputtering during 1 ke V Kr ion irradiation. It is found that at both zero and high fluences the light isotope is preferentially ejected in the near-normal direction; meanwhile, there is a low fluence (1.4 x 10(15) ions/cm2), at which the isotope fractionation is independent of the emission angle in the nearly whole angular range.
