从主要经济体来看，2014年美国经济复苏前景较好，有望成为全球经济的推动力，而日本和欧元区均存在不确定因素，经济仍然存在下滑风险；我国经济仍然以稳定增长为主基调，增速预期与2013年水平相当，呈现小幅波动走势。2014年我国钢铁行业供求矛盾预期出现好转，但仍然维持供过于求的局面，新的一年钢铁业将面对严峻的环保压力与结构调整的艰巨任务，由于政策因素与贸易环境趋于恶化，我国钢铁出口压力仍较大。

报告包括2014年3月下半月钢铁行业的国际要闻、国内要闻、区域要闻以及国际国内企业要闻综述。

我国钢铁工业近年来快速发展取得了很大成就，但是也出现了一些问题，最突出的就是由于产能过剩造成的经营困难和利润大幅度下降。2012年钢铁产量7.16亿吨，占世界产量的46.3%，又创新高。但2012年80家重点大中型钢铁企业累计实现销售收入为35441亿元，同比下降4.3%；实现利润15.8亿元，同比下降98.2%，销售利润率只有0.04%。在这种形势下，钢铁企业需要认真思考今后发展的方式，从国家角度而言，淘汰落后、结构调整、进行企业兼并重组是非常必要的。对于企业而言，同样需要考虑如何走出目前困境的措施，如进行服务化转型，从生产经营型企业向生产生产服务型和技术服务型企业转型；注重产业链延伸、进行产品深加工和多元化经营；走进用户、贴近用户，和用户一起开发新的产品；不断研发新技术、降低成本、提高产品质量；强化工艺与装备创新、从工艺装备创新和研发做差异化等等。

2014年2月份，钢材价格指数弱势运行，继续呈现下滑走势；2月份钢铁行业累计固定资产投资同比小幅增长，增幅不明显；1-2月份我国生铁、粗钢和钢材的产量均呈现同比增长态势；粗钢产量占全球比重有所回落，但仍占据约全球一半产能；2月份钢材出口量明显下降，外部钢材需求低迷，进口量同样降幅明显。整体来看，2月份我国钢铁产量保持增长态势，而需求情况没有明显好转。

2013年1-11月，全国规模以上工业增加值继续保持增长态势，增加值同比增长9.7%.比2012年同期回落0.3个百分点，比2011年同期回落4.3个百分点。预计2013年全年累计同比增长率难以超过10%。分行业来看，黑色金属冶炼及压延加工业呈现下滑趋势，金属制品业、通用设备制造业、专用设备制造业保持稳定增长，汽车制造业增长幅度扩大。

One weak aspect of synthetic polymer materials compared with steel and other metals is that these materials are combustible under certain conditions. Thus, the majority of polymer-containing end products must pass some type of regulatory test to assure public safety from fire. The main objective of this research is to apply combined effects of a catalyst in a clay-based polymer nanocomposite to enhance formation of char from a resin to form a protective layer consisting of char enhanced clay network during burning.

Current V-shaped stainless steel pyrovalve initiators have rectified many of the deficiencies of the heritage Y-shaped aluminum design. However, a credible failure mode still exists for dual simultaneous initiator (NSI) firings in which low temperatures were detected at the booster cap and less consistent ignition was observed than when a single initiator was fired. In order to asses this issue, a numerical framework has been developed for predicting the flow through pyrotechnically actuated valves.

Hydrogen embrittlement of high strength steel is the most predominant unforeseen hurdle since high strength materials show sensitivity to the phenomena and the source of the hydrogen can be anything within the fabrication process, maintenance practice, or the natural corrosion cycle. Historically, the various aerospace defense contractors have each tested in their own manner, which has led to the national standard incorporating many approved test geometries and grey procedures. This work evaluated hydrogen susceptibility over a range of material strength, load level, and hydrogen emitting environment (weight- percent sodium chloride NaCl) which demonstrated performance with parameter ranges, not as pass/fail results, while developing life predictive models for each geometry.
