PL Brąz fosforowy UNS C51100 w postaci pasów o grubości 0,4 mm wyżarzono w temperaturze 600°C. Wyżarzony brąz walcowano na zimno ze zgniotem 20,40,60 lub 80%. Twardość brązu wzrosła od 90 HV do 240 dla Z = 80%. Zgnieciony brąz wyżarzano w temperaturze od 100 do 700°C. Z równania Avrami'ego wyznaczono t[...]
EN UNS C51100 phosphor bronze in a form of 0.4 mm strips was subjected to full annealing at 600°C. The annealed bronze was cold rolled with the cold work of 20,40, 60 and 80%. The bronze hardness increased from 90 to 240 HV for Z = 80%. The cold worked bronze was annealed at the temperatures ranging'fr[...]

EN One type of spheroidal cast iron, with additions of 0.51% Cu and 0.72% Ni, was subjected to precipitation hardening. Assuming that the greatest increase in hardness after the shortest time of ageing is facilitated by chemical homogenisation and fragmentation of cast iron grain matrix, precipitation [...]

EN This scientific paper presents the research on influence of austenitizing temperature on kinetics and evolution of the spheroidal plain cast iron during eutectoid reaction in isothermal conditions. The cast iron has been austenitized in temperatures of 900, 960 or 1020°C. Therewere two temperature v[...]

EN This work presents the qualitative and quantitative changes in the products of isothermal transformation (reaction) in a ductile cast iron austenite after supercooling to the temperature range Ar1. The austenitizing temperature considered in this work was 900, 960 or 1020°C. The eutectoid reaction w[...]
