Abstract(J)老廃スクラップから創製した1180MPa級リサイクル鋼板について引張試験ならびに穴広げ試験を実施し,さらに部品要求性能として重要な疲労強度特性を把握するため荷重方式の異なる疲労試験を実施した.これらの結果から,スクラップから創製したリサイクル鋼板の自動車用鋼板としての適応性について検討する.

Translation

Abstract(E)Tensile tests and hole expansion tests were conducted on 1180 MPa class recycled steel sheets created from scrap, and two types of fatigue tests with different load methods were conducted in order to understand the fatigue strength characteristics that are important for component performance. Based on these results, we will examine the applicability of recycled steel sheets created from scrap as steel sheets for automobiles.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
