HAZ abbr. 热影响区(The heat affected zone)
- It was shown that the impact toughness of HAZ is 50% of base metal.
结果表明,该钢的焊接热影响区的冲击韧性较母材降低50%以上; - It analyses quadratic phase stainless and its metal compound generated from weld seam and HAZ,which affect welded pipe usage property.
分析了双相不锈钢及其焊缝和热影响区中产生的金属间化合物等二次相对焊管使用性能的影响。 - The shortag e of land for construction leads to the necessary utilization of landslides besid es the treatment of landslides,which is a challenge to the prevention of geo-haz ard.
建设用地的严重不足,只能向滑坡等灾害堆积体要地,因此,不仅要治理滑坡灾害,而且还要利用滑坡体,它对地质灾害防治提出了挑战。
