The number of structural components which must operate frequently at repeated loading higher as N ≈ 10 6 -10 7 cycles increases. This fact is serious problem in engineering practice. Fatigue lifetime in the ultra high cycle region (10 8 < N< 10 11 cycles) is therefore studied very intensively with t
## Abstract A composite made from a mixture of iron and copper powders was produced and characterised. The Cu addition favours the production of sintered Fe in the powder metallurgy industry processes. The corrosion behaviour in different electrolytic solution (sodium chloride or hydrochloric, acet
## Abstract The paper deals with the influence of the α/gamma; phase ratio and silicon on the corrosion resistance of low carbon alloyed cast steels in strongly oxidizing media. Electrochemical investigations in 65% HNO~3~ + 5g Cr^6+^ ions/I showed that none of the four tested cast steels, with γ~R
To increase magnetic storage density, it is necessary to develop recording heads using materials with optimised magnetic properties. Several works have revealed the high Bs Co 90 Fe 10 alloys (1.8 ± 2.0 T). However, coercivity of these alloys is too high and the addition of a third element such as c
