The Remote Laboratory and Microhardness Measurement
نویسندگان
چکیده
The measurement of micro-hardness with loads between 0.09807 N and 0.9807 N has been carried out in direct mode (appraiser measured the dimensions of indentations with a measuring device fitted to the micro-hardness tester, a part of microscope) and in modified remote modes. The reference block – certified reference material with defined specified hardness and its uncertainty was used as a specimen, particular measurement involved indirect calibration of tester. The influence of applied load on the measured value of micro-hardness was evaluated by Meyer’s index n and PSR method. The difference between values obtained by particular modes is statistically significant.

The purpose of present research was production ofZr-based alloy as the nuclear fuel cladding by mechanical alloying (MA) and sintering process. Firstly, Zr and Cr powders were mechanically alloyed to produce the refractory and hard Zr-10 wt% Cr alloy, and then, the powder mixtures were consolidated by press and following sintering at temperature of 800˚C min. The phase evolution, microstructura...
