Abstract(J)	金属3D造形の部品適用には造形時間の短縮が求められる．造形時間の短縮には積層厚やエネルギー密度の増加が必要であり，それにより欠陥が生成しやすくなる．本報では造形条件が欠陥率に及ぼす影響を確認し，それらの欠陥が疲労強度に及ぼす影響を確認した． Translation
Abstract(E)	It is necessary to shorten the manufacturing time to manufacture parts using the additive manufacturing technology.But the shortening of manufacturing time increases the number of porosities. In this paper, the relationship between porosity in additive manufactured aluminum materials and fatigue strength is descibed.

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".
