“…The coefficient of thermal expansion of the melt, high temperature strength and viscosity were difficult to measure so that they were calculated using JMatPro (version 5) software. 18, 19 Both Polakova and Kubina 20 and Guo et al 21 reported that the high temperature properties of multicomponent steels calculated using JmaPro were well consistent with the experimental results. In addition, the JmatPro was used to calculate the mechanical and thermal properties of multicomponent Al, Ti, Ni alloys, etc.…”

This study examined the effects of alloying elements, which are normally used to modify the composition of advanced high strength steels, on the expulsion phenomenon during resistance spot welding as well as the effects of alloying elements on the expulsion limit current (ELC). An equation for the ELC prediction was derived from the correlation between the ELC and alloying element: ELC (kA)59.85-0.74Si-0.67Al-0.28C-0.20Mn-0.18Cr. The coefficient of determination between the calculated and measured values was sufficiently high (R 2 50.94). The extent of the effects of the alloying elements on the ELC was in the order of Si, Al, C, Mn and Cr. From the correlations among the ELC and resistivity R, the coefficient of thermal expansion a and yield strength (YS 12008C ), the ELC was calculated to be ELC (kA)59.320.057R20.035a+0.22YS 12008C , and the coefficient of determination was sufficiently high (R 2 50.96).

“…The moment of fracture initiation was predicted using the nCL and the softening method. Damage softening is a method by which the flow stress above this critical value will be reduced to a specified percentage [21,22]. DEFORM ® engineering software exploiting the finite element method (FEM) was used to simulate 3PB.…”

The presented work is aimed at the evaluation of the cold bending capacity of high-borated austenitic stainless steel sheets. Due to their excellent neutron-absorbing capability, borated stainless steels belong to the group of tailor-made structural materials widely used for vertical storage baskets for holding spent nuclear fuel assemblies in cooling pools at dry or wet storage facilities. The basket consists of individual fuel assembly cells. Each polygonal cell is usually welded from several steel strips. It would be advantageous to use bent steel semi-product to avoid welded seams as much as possible. Welded seams are difficult to make, and moreover, they are susceptible to corrosion. However, high-borated stainless steels, because of their boron content, show limited hot and cold workability. Thus, their cold bending capacity would be the primary issue. Their austenitic matrix with embedded hard and brittle boride particles is prone to the evolution and fast propagation of dimple transgranular fracture. This work is focused on the bending aspects of borated steel sheets with respect to the most commonly used hexagonal cell geometry. Experimental results provide practical recommendations for the rack design. The damage criterion has also been proposed using FEM simulations in DEFORM®.
