The highly rigid structure makes extensive use of high-tension steel. It features straight "front side members" with an octagonal "cross-section" and a three-leg support structure, as well as increased application of both high-strength (590Mpa) and ultra-high strength (980MPa) steel. Compared to the previous-generation Lancer, torsional ...
Extensive experimental investigations on structural details and FEM-supported-design methods has shown the high efficiency with conventional S235, S355J2 and fine grain steels, such as S460N, S690QL and even higher strength steels. The achievable material saving makes the HiFIT application in most applications already economically viable.
High-strength steel parts (such as bolts of strength category > 10.9 and nuts of > 9) and components with tensile strength of > 1000 N/mm 2 or > 320 HV are susceptible to hydrogen embrittlement. Galvanic coating processes and pickling with acids have a major influence on the development of hydrogen-induced brittle fractures.
Seismic retrofit (or rehabilitation) strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials (e.g. fiber-reinforced polymers (FRP), fiber reinforced concrete and high strength steel). [5] Increasing the global capacity (strengthening).
In the automotive body repair industry before the 1980s, oxyacetylene gas torch welding was seldom used to weld sheet metal, since warping was a byproduct as well as excess heat. Automotive body repair methods at the time were crude and yielded improprieties until MIG welding became the industry standard. Since the 1970s, when high strength ...
Metal stitching is an industrial technique for repairing cracked and broken cast iron, steel, bronze or aluminium structures and their components. The process is carried out cold, without welding . It allows the repair of cast iron and cast steel , often in-situ, without the distortion from welding , and can be used in other situations where ...
As the strength of steels increases, the fracture toughness decreases, so the likelihood that hydrogen embrittlement will lead to fracture increases. In high-strength steels, anything above a hardness of HRC 32 may be susceptible to early hydrogen cracking after plating processes that introduce hydrogen.
Knifeline attack impacts steels stabilized by niobium, such as 347 stainless steel. Titanium, niobium, and their carbides dissolve in steel at very high temperatures. At some cooling regimes (depending on the rate of cooling), niobium carbide does not precipitate and the steel then behaves like unstabilized steel, forming chromium carbide instead.
