Historically, from a technological point of view, the invention of the crank-connecting rod is considered to be the most important mechanical device of the early fifteenth century in Europe. Bertrand Gille says that this system was unknown before that date and this had considerably limited the appliions of mechanization .

These TPS and propulsion system components will include high temperature ceramic matrix composites (CMCs), such as C/SiC and SiC/SiC. Both hot structure control surfaces and hot wall propulsion system components are two examples of CMCs for which prototype parts have thus far been fabried and subjected to mechanical performance and/or durability testing.

Since startup in 1985, type "S" thermocouples with silicon carbide protection tubes were used for flue temperature measurement and control. With the objective for reducing maintenance time and costs, an extensive test of various coinations of thermocouple and protection tubes types and optical pyrometers was made.
Corrosion of Austenitic Stainless Steel: Mechanism, …
However, since austenitic steels with high silicon and low carbon content tend to crack in the weld region, the filler material must be alloyed to retain 4 to 10% &ferrite in the weld metal [55, 561. Stainless steels, such as AISI type 304 L, are preferentially attacked by hot nitric acid in the crevices which form, for example, during welding or lining, or between the steel and the plastic
