Described herein are additive manufacturing methods and products made using such methods. The alloy compositions described herein are specifically selected for the additive manufacturing methods and provide products that exhibit superior mechanical properties as compared to their cast counterparts. Using the compositions and methods described herein, products that do not exhibit substantial coarsening, such as at elevated temperatures, can be obtained. The products further exhibit uniform microstructures along the print axis, thus contributing to improved strength and performance. Additives also can be used in the alloys described herein.

Additive manufacturing methods using aluminum-rare earth alloys and products made using such methods

Embodiments of surface-hardened aluminum-rare earth alloys and methods of making the alloys are disclosed. In some embodiments, the alloy comprises aluminum and 4 wt % to 60 wt % of a rare earth component X having a maximum solid solubility of &#x2264;0.5 wt % in aluminum. The surface-hardened alloy component has an alloy bulk portion and a hardened alloy surface portion. At least a portion of the hardened alloy surface portion has a Vickers hardness that is at least 30% greater than a Vickers hardness of the alloy bulk portion.

Surface-hardened aluminum-rare earth alloys and methods of making the same

A strain-hardenable stainless steel alloy includes hard secondary phases dispersed in an austenitic primary phase, the alloy including 0.3-0.6% nitrogen by weight.

Cobalt-free, galling and wear resistant austenitic stainless steel hard-facing alloy

A method for evaluating thermal fatigue resistance for a welding consumable alloy can include the following steps: placing a test specimen of a welding consumable alloy in a testing device such that a tensile load and a compressive load can be introduced to the test specimen; heating the test specimen to a first temperature; applying a compressive force to the test specimen while heating the test specimen; cooling the test specimen to a second temperature; and applying a tensile force to the test specimen while cooling the test specimen.

Resistance test method

A high-strength, high-toughness steel alloy includes, generally, about 2.5% to about 4% chromium, about 1.5% to about 3.5% tungsten, about 0.1% to about 0.5% vanadium, and about 0.05% to 0.25% carbon with the balance iron, wherein the percentages are by total weight of the composition, wherein the alloy is heated to an austenitizing temperature and then cooled to produce an austenite transformation product.
