Powder metallurgy of the porous Ti-13Nb-13Zr alloy of different powder grain size
The objective of the present project was to determine the effects of powder granulation (fraction of grain size) for the Ti-13Nb-13Zr alloy, produced by powder metallurgy, on its porosity, grain cohesion, compressive strength, and Young`s modulus. Two powder fractions, 45–105 µm, and 106–250 µm were applied. The 50 mass pct of NH4HCO3 was added as a space holder. The specimens were in compaction stage uniaxially pressed at pressure...

Strength deterioration of 26H2MF and 34HNM steels used in ship engines: hydrogen factor
Badano podatność stali 26H2MF i 34HNM poddanych różnej obróbce cieplnej na niszczenie wodorowe. Badania wykonano metodą powolnego rozciągania z szybkością 10-6 s-1. Określano wytrzymałość, wydłużenie, przewężenie i energię zniszczenia. Stwierdzono znaczna degradację w 0,01 M kwasie siarkowym z dodatkiem arszeniku. Wykazano istnienie korelacji między obróbką cieplną i stopniem degradacji. Efekty przypisano pułapkowaniu wodoru.

Biocompatibility and bioactivity of load-bearing metallic implants
The main objective of here presented research is to develop the titanium (Ti) alloy base composite materials possessing better biocompatibility, longer lifetime and bioactivity behaviour for load-bearing implants, e.g. hip joint and knee joint endoprosthesis. The development of such materials is performed through: modeling the material behaviour in biological environment in long time and developing of new procedures for such evaluation;...
