About 80%of all molybdenum mined in the world(not including units recovered via recycling)is used as an alloying element in iron and *** general,the intensity of molybdenum use in China is still lower than in more highly developed regions such as the USA and *** difference is manifest in both carbon steels and stainless steels,suggesting a significant opportunity for more widespread use of molybdenum in the future as China follows its self-reliance policy,calling for more sophisticated *** market development,as being pursued by the International molybdenum Association(IMOA),is a key asset in that *** article summarizes some key facts on molybdenum mining,use and market development in China.

A Strategy of Avoiding Delayed Fracture in Ultrahigh Strength Automotive Steels by Nb Microalloying

引用

Journal of Iron and Steel Research International 2011年第S1期18卷 893-897页

作者： Hardy Mohrbacher NiobelCon bvba 2970 SchildeBelgium

Recently the automotive industry has been confronted with the phenomenon of delayed *** phenomenon was not relevant in earlier years since the strength level of the steels was generally below a critical ***,delayed fracture is not necessarily related to an absolute strength value but rather to microstructural features as well as pre-existing micro-damage in the material that are likely to occur in ultrahigh strength *** microalloying in combination with appropriate processing can effectively help to improve the resistance against delayed fracturing in such *** paper outlines a strategy how to achieve this based on microstructural control and hydrogen trapping.
