Abstract(J)	表面欠陥を有するアルミニウム合金にボールバニシング(BB)を施工し，その疲労強度を測定した．BBは表面粗さを低減させるとともに，圧縮残留応力を付与することが可能であった．これらの効果により，BBはアルミニウム合金の外観を向上させるだけでなく，表面欠陥を無害化し，疲労強度を向上できることを明らかにした． Translation
Abstract(E)	Ball burnishing (BB) is a surface finishing process that involves moving the tool while pressing it against the workpiece under rolling contact. BB was performed on an aluminum alloy specimens containing a surface defect, and the fatigue strength of the specimens was measured.Ball burnishing reduces surface roughness and induces compressive residual stress. These effects resulted in improved appearance and increased fatigue strength of the aluminum specimens.

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
