Steady state creep behaviour of silicon carbide

The roles of volume fraction and size of reinfrecement on the steady state creep behaviour of pure aluminium matrix-silicon carbide particulate composites have been studied in the temperature range 623–723 K.The observed apparent stress exponents are higher than 15 and apparent activation energy is 249 kJ mol −1.By considering the existence of a threshold stress, the data for 1.7 μm

Tungsten | Plansee

Tungsten was first found in the Ore Mountains of Central Europe in the Middle Ages during the process of tin reduction. However, at that time it was considered to be an unwanted accompanying element. The tungsten ore facilitated slag formation during the reduction of tin and consequently impaired the yield.

Titanium - Wikipedia

2019-4-20 · Titanium is a chemical element with syol Ti and atomic nuer 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791, and was named by Martin Heinrich
