Plastic properties of cold-deformed ironbased sintered materials
Cold plastic forming of sintered metal powders has limited practical application because of, among others, the deformation degree and initial porosity of preforms. Cold forming is combined with a very drastic drop of pla...
Constrained/unconstrained solidification within the massive cast steel/iron ingots
Some properties of the ingot and especially of the steel forging ingots depend on the ratio of a columnar structure area to an equiaxed structure area created during solidification. The CE transition is fundamental phe...
Effect of alloying elements on branching of primary austenite dendrites in Ni-Mn-Cu cast iron
Within the research, determined were direction and intensity of influence of individual alloying elements on branching degree of primary austenite dendrites in austenitic cast iron Ni-Mn-Cu. 30 cast shafts dia. 20 mm wer...
Sigma phase in the cast alloy based on the FeB3BAl intermetallic phase
The paper presents study results for cast alloy based on the FeB3BAl intermetallic phase. The study material was Fe-28Al-5Cr-1Mo-0,1Zr- 0,005B% at. alloy in the cast state. The microscopic research, phase analysis with X...
Microwave Absorption by Used Moulding and Core Sands
The paper presents measurement results of standing wave ratio to be used as an efficiency indicator of microwave absorption by used moulding and core sands chosen for the microwave utilization process. The absorption mea...
