Popis:	Solid state reaction method was used to prepare samples of Bi1.6Pb0.4Sr1.8Ba0.2Ca2Cu2.2Ni0.8O10+d. Superconducting and mechanical properties by Vickers microhardness measurements have been carried out to examine the effects of pressure. Electrical measurement demonstrates the best transition temperature was under 0.7 GPa. An improvement of mechanical properties was found when the pressure increases from 0.3 GPa to 0.9 GPa. On the other side an increases of the pressure to 1.1 GPa decrease in the micro hardness, Young modulus and yield strength.
