Abstract:
The paper is focused on investigation of the deformation behaviour of two nickel alloys - IN 713 LC and MAR M-247, delivered in the as-cast state. The aim was to determine physically the nil-strength temperatures and on the basis of tests by uniaxial tension to create 3D maps of plastic and strength characteristics of both these alloys. [..]

Abstract:
During the last years there is a strong tendency of automotive industry to achieve suitable compromisebetween effort to lower environmental load at car operation by lowering its weight (thus to lower thickness of used parts) and on the other hand there is tendency to still increase the safety of passengers by utilization ultra-high strength materials. That is why these days are more and more important strength materials and alloys based e.g. [..]

Abstract:
These days there can be observed still increases requirement about products quality at keeping low price level. Such contending claims of market environment force producers in every branch of engineering industry to innovate their technological procedures and to process new progressive materials with specific utility properties.

Abstract:
The subject of the research is study of an elastic-plastic behavior of the materials, S355N steel and Domex700MC steel, which are used in welded construction parts of car bodies, the Domex700MC steel is used with the intention of decreasing the weight of the parts. The solved problem is to determine the local static parameters of the steels without the possibility to use the standard mechanical testing. [..]

Abstract:
On the surface of a 17-4 PH stainless steel, powders from the cermet group were submitted, using the plasma thermal spray technique on a METCO SULZER installation. Thereafter, a part of the sprayed samples were remelted at the surface withu the Nd:YAG laser beam, on a Trumpf HL 123 LCU installation. [..]

Abstract:
This work contains a detailed description of the influence of continuous heating from as-quenched state on microstructure development in the 17-4PH steel. The temperature ranges of the phase transformations occurring during heating from the as-quenched state (tempering) were determined from dilatometric tests. [..]

Abstract:
This work presents results of the analysis of phases formed in a SUPER 304H steel during a medium-term static isothermal ageing (675 °C/15000 h). The investigations of the precipitates were especially focused on the occurrence of sigma-phase because its formation leads to the serious embrittlement.The evaluation and distribution of brittle sigma-phase were determined on macroscopic level by using light microscopy/colour etching.
