Translation

Abstract(E)In this study, tensile tests and tightening tests for magnesium alloy bolts and aluminum alloy bolts have been conducted to investigate the effectiveness of magnesium alloy bolts. The magnesium alloy bolts used in the tests were made of AZ31 and AZX912 (9Al-Zn-2Ca) magnesium alloy, and the aluminum alloy bolts were made of A5056 aluminum alloy. Test results showed that the tensile strength of the aluminum alloy bolts was higher than that of the magnesium alloy bolts. However the results of the tightening tests indicated that the tightening strength of the magnesium alloy bolts was greater than that of the aluminum alloy bolts.

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.
