J. Jaworski, T. Trzepieciński: Faculty of Mechanical Engineering and Aeronautics, Rzeszow University of Technology, Rzeszów, Poland This paper presents the results of research on the determination of the coefficient of thermal conductivity and hot hardness of cutters made of selected grades of low-alloy high-speed steels, HS 6-5-2 and HS3-1-2. The investigations of hot hardness and yield stress...

In real conditions, austenitic stainless steels solidify in non equilibrium and a two phases microstructure of austenite and ferrite is formed 1 . The aim of this work was to investigate the behaviour of both phases at tensile testing, especially to find out an eventual difference in the relaxation of the deformation energy and the effect of the two phases microstructure in workability. To achi...

In this work, tensile and yield stress and tensile and yield strain of oblique layer functionally graded steels produced by electroslag remelting were investigated. Functionally graded steels containing ferrite, austenite, bainite, and/or martensite layers may be fabricated via diffusion of alloying elements during the remelting stage. Tensile and yield stress and tensile and yield strain of fu...

In this paper an exhaustive scientific work is performed, by means of metallographic and scanning electron microscope (SEM) techniques, the microstructural defects exhibited pearlitic steels their evolution with manufacturing process cold drawing, analyzing consequences such on isotropic/anisotropic fracture behavior different steels. Thus, objective establishment a relation between damage To e...
