Participation of liquid phase in solidification cracking of cast alloys
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
According to widely accepted W.S, Pellini “liquid -film” theory, hot tears initiate at the stage of solidification, when the last solidifying liquid distributed in a film-like morphology separates solid grains. When shrinkage ...
Mechanical properties of Ni3Al alloyed with boron and zirconium elements
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
The present investigation was carried out to determine the influence of the different contents of zirconium and small boron addition on the microstructure and mechanical characteristic of high temperature deformation on ...
The effect of nitrogen and microalloying additions of vanadium and titanium on mechanical properties of 40Cr7 steel
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
The effect of nitrogen and microalloying additions of V and V+Ti on the mechanical properties of heat treated 40Cr7 steel was investigated using four laboratory steels. Two variants of heat treatment were applied: normalizing ...
Mössbauer spectroscopy in the materials science and engineering
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
The paper is aimed at the review of the basic features of the Mössbauer spectroscopy and its application in the selected areas of the materials science with the particular attention paid to the physics of magnetically ...
The influence of the procedure of heating on the properties of the AlSi11/Al2O3 joints
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
The development of alloys and ceramic joining technology in modem scopes of industry is largely related to the study of the conditions technology of joining the materials of different physical and chemical properties. The ...
Crystallisation of Ni64Cu9Fe8P19 glass forming alloy studied by mössbauer spectroscopy and x-ray diffraction
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
The Ni64Cu9Fe8P19 melt spun ribbon was cast using melt spinning. The ribbon in as-cast state was characterised with use of transmission electron microscope (TEM) and X-ray diffraction (XRD). Differential thermal analysis ...
Functionally graded materials prepared using pm methods
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
In this work the state of art related to obtaining, properties and application of functionally graded materials is presented. Functionally graded materials (FGM) secure obtaining of cutting tools of wear resistance surface ...
Thermomechanical treatment in forging process of medium-carbon microalloyed steel
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
Utilization of thermomechanical treatment in forging medium-carbon alloyed steel with microaddition of titanium is presented. Results of forging tests carried out in industrial conditions with a use of a high-speed forging ...
Al2O3 cutting properties improvement
(Institute of Technology, Pedagogical University, Cracow, cop. 2006, 2006)
Alumina base ceramic tools have mainly been used as environmentally-friendly cutting tools, because they have particularly high temperature limit and allow dry cutting without or with limited quantity of coolant. The main ...
