DESCRIPTION:Speakers: Prabhat Pant (Linköping University)\nAdditive manuf
 acturing (AM) of components made out of metals using powder and laser has 
 been in increasing demand especially in the sector of aerospace\, medical 
 sectors\, etc. With AM\, parts with complex geometries can be manufactured
  easily in comparison to the traditional ones. However\, with the ease of\
 nmanufacturing complex parts\, several issues must be tackled to get a goo
 d quality party without losing its mechanical integrity. One of such issue
 s is the control of residual stresses (RS). These RS are generated mainly 
 due to the temperature difference between the consecutive layers while pri
 nting. For a comprehensive and systematic study of different process param
 eters such as print orientations and scan strategies two separate studies 
 on L-shaped geometry printed out of IN718 superalloy were done. The first 
 study was on print orientation\nwhere parts were printed in different orie
 ntations namely: horizontal (HB)\, vertical (VB)\, and 45° angle (45B)\, 
 and for the second study parts were printed in the vertical orientation wi
 th different scan strategies. With the help of neutron diffraction\, RS di
 stribution in the bulk of the sample and the influence of these printing p
 arameters on the RS magnitude and distribution were studied. For the print
  orientation study\, it was found that\npart built in a Vertical orientati
 on has the highest magnitude of RS and for the scan strategies' influence\
 , it was found that different scan strategies can lead to the reduction of
  RS in the same part printed in the vertical orientation. From the data av
 ailable from the experiment\, a simplified FEM model to predict the RS due
  to print orientation was also established. The model can predict the RS d
 istribution trend similar to that measured ones but with a higher magnitud
 e of stresses. Further data from the neutron diffraction results can be us
 ed to calibrate the existing models for the prediction of RS in AM or to v
 erify new models as well.\n\nhttps://lindico453.srv.lu.se/event/214/contri
