The metallic mouth of a perishable body pot from Monterenzio Vecchia (BO) was studied. A metallographic and microanalytical study was carried out, to obtain information useful to understand material characteristics and propose hypothesis about manufacture process. Observations allowed to gain data relatively to alloy composition and inclusions...

A commonly accepted opinion is that steam treatment increases the corrosion resistance of P/M ferrous materials. To confirm the scanty literature data, the behaviour of steam treated material has been investigated. The test samples have been pistons for refrigerator compressors, namely P/M parts typically steam treated. The corrosion resistance...

Il processo di sinterotempra è generalmente applicato ad acciai ad alto tenore di elementi di lega che, sottoposti a velocità di raffreddamento medio-alte dopo il normale ciclo di sinterizzazione, raggiungono durezze elevate (anche superiori ai 500 HV5) [1, 2]. Tuttavia, nella pratica industriale, per determinati utilizzi (es.: levette per...

The Radcliffe wave (RW) is a recently discovered sinusoidal vertical feature of dense gas in the proximity of the Sun. In the disk plane, it is aligned with the Local Arm. However, the origin of its vertical undulation is still unknown. This study constrains the kinematics of the RW, using young stars and open clusters as tracers, and explores...
