. Based on the obtained results, it was assumed that in the case of areas in which only nickel borides occurred (percentage of chromium borides was equal to 0), the corresponding indentation hardness...)). It corresponded to the presence of chromium borides. Based on results of XRD analysis and pointwise X-ray microanalysis it was found that lighter areas in compact borides zone were mixture of nickel borides (NiB......

The results indicated that cracking susceptibility was increased with increasing the laser output power... presents the very low precision because of the two reasons. On one hand, based on different models, different equations are derived and applied to calculating fracture toughness, which leads......
, mechanical properties and shape-memory effect were investigated. The results show that the density and size of porosity vary based on the sintering time and temperature, in which the smallest size...-like and plate-like morphologies, and their volume fractions vary based on the sintering time and temperature. The β phase represents the largest phase due to the higher content of β stabilizer element......
