Corrosion creep alloys

The nickel-based alloys show a wider range of application than any other class of alloys. These alloys are used as corrosion-resistant alloys, heating elements, controlled expansion alloys, creep-resistant alloys in turbines and jet engines, and high-temperature, corrosion-resistant alloys. [Pg.235]

Recent progress in science and technology is leading to more corrosion-resistant alloys and is promising to discover the real passive Mg alloys. Original new creep-resistant alloys for structural purposes and new appropriate snrface preparation, pre-treatments and coatings will open the door to this metal for... [Pg.108]

Corrosion creep and fatigue behavior of magnesium (Mg) alloys... [Pg.365]

Key words magnesium alloys, corrosion creep, corrosion fatigue, buffer solution, NaCl, Na2S04. [Pg.365]

Corrosion creep of diecast Mg-5A1 and Mg-9Al-lZn alloys anodized by a 8p.m thick coating showed that anodic coating delays metal dissolution facilitating plastic deformation of the stressed metal, and for this reason alone increases the corrosion creep life of metals (Fig. 9.15). For instance, time-to-fracture of anodized Mg-5A1 alloy increases from 340 to 637 hours... [Pg.383]

Cracks filled by phenolic resin in the vicinity of the coated surface of AZ91D alloy after a corrosion creep test in buffer solution (dark area is a-Mg solid solution light area is Mg-i7Ali2 phase). 1 -coating 2 - the crack in coating 3 - the crack in the bulk of the alloy. [Pg.386]

The synergistic effect of corrosion and stress on the creep behavior of magnesium and diecast Mg alloys named corrosion creep has been investigated. We can conclude that at room temperature marked plasticization and fracture are observed in sodium tetraborate buffer solution even under stresses less than 40% of TYS as compared with common low-temperature creep in air almost... [Pg.386]

Anodized Mg alloys reveal a significantly longer creep life than uncoated diecast alloys. Pure magnesium shows transgranular fracture in corrosion creep tests against the ordinary intergranular fracture of alloys in corrosive media. [Pg.387]
