Tungsten steel is a sintered composite material containing at least one kind of metal carbide, and tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, and tantalum carbide are common components of tungsten steel. The grain size of the carbide component is usually between 0.2-10 ...
Surprisingly, modern titanium bicycle frames are much more likely to break than steel frames. Not because of strength, but just plain defective materials. There are applications where titanium may be stronger, or more reliable, but bicycle fame building is not it. In the early days of the ...
6 shows the historical price of cobalt, nickel, titanium and ferromanganese according to references32,33,34. Supplementary Table 2 shows the alloy composition of different steels according to reference17. Tensile strength data was obtained from the same reference for the different steels and from ...
the strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium tube has high corrosion resistance to chloride, sulfide and ammonia. Titanium has higher corrosion resistance in seawater than aluminum alloys, st...

Otherwise, the steel alloy would have the natural crystal structure of iron and chromium, which is body-centered cubic (bcc) ferrite, as the parent phase, and alloying elements that make the alloy behavior like this include molybdenum, niobium, titanium, vanadium, and silicon. A stable ...
Parts made of a heat-treated alloy steel having a minimum tensile strength of 700 N/mmand a notch toughness of at least 55 joules, wherein the alloy steel is a Mn/Cr/Nb alloy steel of lower alloy content than has hitherto been used to provide the desired strength/toughness properties.收...
The ultra-high strength is the result of the hardening mechanism during the aging treatment, where the precipitation of nanometre-sized intermetallic particles (Ni3(Mo, Ti), Fe2Mo) takes place21. These particles are homogenously distributed in the low-carbon martensitic microstructure, where they ...
In this work, ultra-low dilution rate Inconel 625 coatings with a thickness of ~534.4 μm were prepared by high-speed laser cladding technique on the Q245R steel. The XRD and TEM results show that the Inconel 625 coatings are mainly composed of the Nb
Friction stir welding (FSW) is a novel solid state joining technique that is presently attracting significant attention on welding of hard metals such as steel and titanium [9], [10], [11]. FSW has appeared as an easy, ecological and promising productive welding method that reduces material ...
