Aerospace superalloys derive their structural integrity from solid-solution strengthening elements like molybdenum, tungsten, and cobalt, combined with the controlled precipitation of intermetallic phases. For instance, Inconel 718 relies heavily on niobium and titanium to form the body-centered tetragonal gamma-double-prime (\u03b3&#8221;) phase, providing exceptional yield strength up to 650\u00b0C.<\/p>\n<p data-path-to-node=\"7\">However, as turbine inlet temperatures escalate beyond 700\u00b0C, the metastable \u03b3&#8221; phase rapidly coarsens and transforms into the thermodynamically stable, but structurally weaker, delta (\u03b4) phase. In such aggressive thermal regimes, alloys like Waspaloy or Udimet 720, which precipitate the face-centered cubic gamma-prime (\u03b3&#8217;) phase (Ni3(Al,Ti)), become mandatory. The volume fraction, morphology, and thermal stability of these \u03b3&#8217; precipitates dictate the alloy&#8217;s resistance to dislocation glide under sustained centrifugal stresses. Furthermore, trace additions of boron and zirconium are critical; they segregate to grain boundaries, reducing grain boundary sliding and significantly improving creep ductility at elevated temperatures.<\/p>\n<table data-path-to-node=\"8\">\n<thead>\n<tr>\n<td><strong>Grade de l'alliage<\/strong><\/td>\n<td><strong>M\u00e9canisme de durcissement primaire<\/strong><\/td>\n<td><strong>Temp\u00e9rature de fonctionnement maximale (\u00b0C)<\/strong><\/td>\n<td><strong>Limite d'\u00e9lasticit\u00e9 \u00e0 650\u00b0C (MPa)<\/strong><\/td>\n<td><strong>Principaux \u00e9l\u00e9ments d'alliage (poids %)<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"8,1,0,0\"><b data-path-to-node=\"8,1,0,0\" data-index-in-node=\"0\">Inconel 718<\/b><\/span><\/td>\n<td><span data-path-to-node=\"8,1,1,0\">Precipitation (\u03b3&#8221;)<\/span><\/td>\n<td><span data-path-to-node=\"8,1,2,0\">650<\/span><\/td>\n<td><span data-path-to-node=\"8,1,3,0\">~1030<\/span><\/td>\n<td><span data-path-to-node=\"8,1,4,0\">Ni (50-55), Cr (17-21), Nb (4.7-5.5)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"8,2,0,0\"><b data-path-to-node=\"8,2,0,0\" data-index-in-node=\"0\">Waspaloy<\/b><\/span><\/td>\n<td><span data-path-to-node=\"8,2,1,0\">Precipitation (\u03b3&#8217;)<\/span><\/td>\n<td><span data-path-to-node=\"8,2,2,0\">870<\/span><\/td>\n<td><span data-path-to-node=\"8,2,3,0\">~760<\/span><\/td>\n<td><span data-path-to-node=\"8,2,4,0\">Ni (Base), Cr (18-21), Co (12-15)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"8,3,0,0\"><b data-path-to-node=\"8,3,0,0\" data-index-in-node=\"0\">Ren\u00e9 41<\/b><\/span><\/td>\n<td><span data-path-to-node=\"8,3,1,0\">Precipitation (\u03b3&#8217;)<\/span><\/td>\n<td><span data-path-to-node=\"8,3,2,0\">900<\/span><\/td>\n<td><span data-path-to-node=\"8,3,3,0\">~950<\/span><\/td>\n<td><span data-path-to-node=\"8,3,4,0\">Ni (base), Cr (18-20), Co (10-12)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"8,4,0,0\"><b data-path-to-node=\"8,4,0,0\" data-index-in-node=\"0\"><a href=\"https:\/\/www.nickelcasting.com\/ar\/%d8%b3%d8%a8%d8%a7%d8%a6%d9%83-%d8%a7%d9%84%d9%86%d9%8a%d9%83%d9%84\/%d8%b3%d8%a8%d8%a7%d8%a6%d9%83-%d8%a7%d9%84%d9%86%d9%8a%d9%83%d9%84-%d9%87%d8%a7%d8%b3%d8%aa%d9%8a%d9%84%d9%88%d9%8a\/%d9%87%d8%a7%d8%b3%d8%aa%d9%8a%d9%84%d9%88%d9%8a-x\/\">Hastelloy X<\/a><\/b><\/span><\/td>\n<td><span data-path-to-node=\"8,4,1,0\">Solution solide<\/span><\/td>\n<td><span data-path-to-node=\"8,4,2,0\">1200 (limite d'oxydation)<\/span><\/td>\n<td><span data-path-to-node=\"8,4,3,0\">~280<\/span><\/td>\n<td><span data-path-to-node=\"8,4,4,0\">Ni (base), Cr (20,5-23), Fe (17-20)<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 data-path-to-node=\"9\">R\u00e9sistance \u00e0 l'oxydation et \u00e0 la corrosion \u00e0 haute temp\u00e9rature<\/h2>\n<p data-path-to-node=\"10\">La r\u00e9sistance m\u00e9canique n'a plus d'importance si le mat\u00e9riau de base ne peut pas survivre \u00e0 l'oxydation agressive et \u00e0 la corrosion \u00e0 chaud pr\u00e9sentes dans les flux d'\u00e9chappement des turbines.

Cependant, \u00e0 des temp\u00e9ratures extr\u00eames d\u00e9passant 1000\u00b0C, la chromie s'oxyde davantage en CrO3 volatile.
