1马氏体对铁素体-贝氏体双相钢机械性能的影响显示文摘本文研究的是4种热轧双相钢的组织与性能之间的关系,这4种双相钢中的马氏体相含量在2%~6%之间。研究发现这些双相钢中含有少量马氏体(2%或更多)可以产生连续的屈服行为,具有一般双相钢的特点。这些双相钢中含有大量的贝氏体(47%~74%),不但具有高的机械性能的同时还具有足够的延性。这些钢的应变硬化指数相当低。与普通的C—Mn—Si钢相比,这些双相钢中的合金元素如Cr,Mo和V能显著提高强度。A.SAHA PODDER 2010现代冶金(内蒙古)2010,,2:2

4Maximum mass of anisotropic charged strange quark stars in a higher dimensional approach(D≥4)显示文摘In this article,a new class of solutions of Einstein-Maxwell field equations of relativistic strange quark stars obtained in dimensions D≥4,is shown.We assume that the geometry of space-time is pseudo-spheroid,embedded in Euclidean space of(D-1)dimensions.The MIT bag model equation of state(henceforth EoS)is employed to study the relevant properties of strange quark stars.For the causal and non-negative nature of the square of the radial sound velocity(vr2),we observe that some restrictions exist on the reduced radius(b/R),where R is a parameter related to the curvature of the space-time,and b is the radius of the star.The spheroidal parameter A used here defines the metric potential of the grrcomponent,which is pseudo-spheroidal in nature.We note that the pressure anisotropy and charge have some effects onλ.The maximum mass for a given surface density(ρs)or bag constant(B)assumes a maximum value in dimension D=5and decreases for other values of D.The generalized Buchdahl limit for a higher dimensional charged star is also obeyed in this model.We observe that in this model,we can predict the mass of a strange quark star using a suitable value of the electric charge(Q)and bag constant(B).Energy and stability conditions are also satisfied in this model.Stability is also studied considering the dependence of the Lagrangian perturbation of radial pressure(Δpr)on the frequency of normal modes of oscillations.The tidal Love number and tidal de-formability are also evaluated.A.Saha K.B.Goswamiy B.Dasz P.K.Chattopadhyayx 2023Chinese Physics C2023,47,1:0
5Anisotropic strange quark star in Finch-Skea geometry and its maximum mass for non-zero strange quark mass(m_(s)≠0)显示文摘A class of relativistic astrophysical compact objects is analyzed in the modified Finch-Skea geometry described by the MIT bag model equation of state of interior matter,p=1/3(ρ-4B),where B is known as the bag constant.B plays an important role in determining the physical features and structure of strange stars.We consider the finite mass of the strange quark(m_(s)≠0) and study its effects on the stability of quark matter inside a star.We note that the inclusion of strange quark mass affects the gross properties of the stellar configuration,such as maximum mass,surface red-shift,and the radius of strange quark stars.To apply our model physically,we consider three compact objects,namely,(ⅰ) VELA X-1,(ⅱ) 4U 1820-30,and(ⅲ) PSR J 1903+327,which are thought to be strange stars.The range of B is restricted from 57.55 to Bstable(MeV/fm3),for which strange matter might be stable relative to iron(^(56)Fe).However,we also observe that metastable and unstable strange matter depend on B and ms.All energy conditions hold well in this approach.Stability in terms of the Lagrangian perturbation of radial pressure is studied in this paper.B.Das K.B.Goswami A.Saha P.K.Chattopadhyay 2023Chinese Physics C2023,47,5:0
