Tungsten has the highest yield and tensile strength of any pure metal, making it arguably the strongest metal in the world. And yet, it's not the hardest metallic element or even the strongest metal by weight. Speaking of pure metal, determining the strongest metals also calls into question:...
Currently the highest strength steels typically have a maximum tensile strength of 2GPa. In addition, the fatigue behaviour of the MMC was found to be better than other MMCs, which are made using a titanium matrix. Finally, the authors present high-resolution microscopy of the optimised titanium...
A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel5. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel. BASIC PROCESSA steel making process ...

flexural stiffness exhibited by each of the zones. For clubs that have a hitting face made from a single material, such as titanium or titanium alloy, the area of highest thickness corresponds to the portion with the highest flexural stiffness. Flexural stiffness (FS) of each portion is ...
9,the cast steel ZG200- 400statement is correct A200is the minimumvalue of yield point, and B200is the lowest tensile strength C400is the minimum yield point, and D400is the highest tensile strength 10.The room temperature obtained after quenching is as follows A austenite, B cementite, C ba...
Constant heating rate hydrogen thermal analyses were carried out for weld metals with tensile strengths in the range 490–1000 MPa. It was found that the hydrogen diffusion rate in the highest strength weld metal is lower by a factor of five than that in a lower strength variant. The hydroge...
The results showed that the jute fibers sandwiched by the basalt fibers had the highest tensile strength, elastic modulus and interlaminar shear strength (ILSS) values; these were 213 MPa, 39.5 GPa, and 16.67 MPa, respectively. In contrast, these values were 139 MPa, 29.6 GPa...

The hardest known metal is steel alloy, which is often made even harder by adding carbon and other elements. With a tensile strength of 0.84 GPa (122,000 psi) and a yield strength of 0.64 GPa (67,000 psi), carbon steel is surpassed in hardness only by very hard nonmetals, such as ...
