A near-β or β titanium alloy having high strength, high ductility, and high toughness which is capable of coil rolling at a high temperature and recoiling for high productivity, and a process for producing said titanium alloy. The titanium alloy contains not more than 1.0% (excluding 0%)...
Rubber reigns supreme in terms of toughness. It has enough strength to withstand a good amount of force before it deforms but does not fail right away upon deformation. It is this combination of strength and ductility which makes rubber a uniquely tough material. What is strength? Of the thr...
A general procedure is discussed whereby the fatigue process is separated into three stages of crack initiation, crack propagation and final fracture, Relations for these three stages are discussed making it possible to examine the relative roles of ductility, tensile strength and fracture toughness in...
It is interestingly noted that the tensile ductility of E,V–SiO2/PDCPD composites is dramatically improved by 862% through incorporation of 0.2?wt% E,V–SiO2. More significantly, the maximum tensile strength and impact toughness are enhanced by 22% and 99% via addition of E,V–SiO2. Exce...
Moreover, currently emerging high-strength constructional steel (also known as high-performance steel) can further achieve an optimized balance of strength, weldability, ductility, toughness, corrosion resistance, and formability. Such steels have promising applications in worldwide major projects [1-3]...
Effects of Composition on Ductility and Toughness of Ferritic Stainless Steels Development of dual-phase PM stainless steels reflects the growing need for higher strength, coupled with ductility and toughness. In the present study, a... M Semchyshen A P Bond, H J Dundas 被引量: 11发表: 1972...
Sloof3 Bones of humans and animals combine two unique features, namely: they are brittle yet have a very high fracture toughness linked to the tortuosity of the crack path and they have the ability to repeatedly heal local fissures such that full recovery of overall mechanical properties is...
The measured fracture toughness is then dependent on the size of a plastic zone that is formed under the most highly constrained conditions. In order to develop an extended yield zone, the initiation of plastic flow is not enough. The material must also be able to draw and strain harden. ...
The microalloyed low-carbon steel acquired a continuous yield with high yield strength, a gigapascal level of ultimate tensile strength (i.e., ~ 1.1 GPa), and a very low yield ratio (i.e., 0.55) while retaining reasonable ductility and toughness when compared to the preheat-treated ...
HSLA steels demonstrate unique properties, such as high strength, excellent ductility, and good weldability, and also exhibit outstanding low temperature impact toughness superior to that of high yield strength (HY) steels. HSLA steels have much improved weldability compared to HY steels [1]. Now-...
