To improve the mechanical characteristics of laser welded ferrite-pearlite steel joints the ultrasonic-assisted laser welding was used. As a result of ultrasonic action the welded samples obtained at non-optimal parameters had a strength of 98% compared to the samples welded at optimal parameters ...
Microstructure and mechanical properties of dual phase steel with ferrite and martensite were studied by means of optical microscope(OM),scanning electromicroscopy(SEM) and tensile tests.The results show that for the steel with type A microstructure of ferrite and pearlite and type B microstructure of...
In the second part of the work, mechanical tests have been carried out and the influence of the fractal morphology of acicular ferrite on the mechanical properties of three medium carbon microalloyed steels has been studied. The results point out an exponential relationship bet...

The mechanical properties of SiC based composites reinforced with different types of fabrics have been investigated, in conjunction with the detailed analyses of their microstructures. The thermal shock properties of SiC/SiC composites were also examined. All composites showed a dense morphology in the ...
