Fatigue crack propagation in iron and six Fe Si and Fe Ni binary alloys was studied at temperatures from 123 to 296 K to determine alloy and temperature effects. Crack growth rates were observed to decrease initially with decreasing temperature for all alloys. At some temperature below the ductil...
Fatigue and pregnancy.This is most common during the first trimester (12 weeks), but it may happen at any point during pregnancy. It may stem from hormonal changes, extra weight, sleep troubles, low iron levels, or raised breathing and heart rate. (You have to pump more blood during pregn...
High Strength Low Alloy (HSLA) Steels in Building Construction Majority of the buildings,including industrial buildings,are constructed using either structural steel (plates and structural shapes) or deformed bar steel... SK Siva,SG Jansto - 《Journal of Iron and Steel Research(International)》 被...
Transfusion of blood products is a common medical procedure, and maintaining adequate blood supply depends on the unpaid donation of a small share of the general population. The absence of pre-donation testing for iron status allows many... BR Spencer 被引量: 0发表: 2017年 加载更多来源...
摘要: The article reviews the article "Effect of iron supplementation on fatigue in nonanemic menstruating women with low ferritin: a randomized controlled trial," by P. Vaucher et al published in the 2012 issue of the "Canadian Medical Association Journal." 年份: 2013 收藏...
The paper deals with the comparison of fatigue properties of nodular cast iron at low and high frequency cyclic loading. The specimens from three melts of nodular cast iron with different microstructure and mechanical properties were used for experiments. Fatigue tests were carried out at low and ...
Effect of Boron on CGHAZ Microstructure and Toughness of High Strength Low Alloy Steels Effect of boron on the microstructure and impact toughness in the coarse-grained heat-affected zone(CGHAZ)of two high strength low alloy steels,boron-free ... Han,YANG,Xi-xia,... - 《Journal of Iron and...
Models of magnetic field generation in partly stable planetary cores: Applications to Mercury and Saturn A substantial part of Mercury's iron core may be stably stratified because the temperature gradient is subadiabatic. A dynamo would operate only in a deep ... UR Christensen,J Wicht - 《Icar...
Magnesium, iron, zinc, copper and chromium have the potential to affect physical performance.142 Researchers have shown that vitamin and mineral deficiencies may result in decreased physical performance, and their supplementation improves physical performance in persons with preexisting deficiencies. For ...
