1.고용체 강화 (Solid Solution Strengthening)
일반적으로 용매 원자의 격자에 용질 원자가 고용되면 순금속보다 강한 합금이 된다. 이는 고용체를 형성하면 그것이 치환형 고용체이건 침입형 고용체이건 간에 격자의 뒤틀림 현상이 생기고, 따라서 용질 원자의 근처에 응력장(應力場, stress field)이 형성된다.

분산성은 분말입자가 골고루 물에 퍼져 흩어지는 성질을 말하며, 덩어리가 클수록 분산성은 좋지 않다. 침강성이 좋은 분말은 보통 분산성이 좋다. 용해도는 분말입자가 물에 녹는 정도를 말하는데 이것은 분말의 화학적 성분조성과 물리적 상태에 따라 달라진다. 건조

Basta vapore.
The apprentice throws a lever. A shunt near the furnace
turns. Steam escapes upwards. The machine immediately
slows down. Da Vinci oh-so-gently coughs and moves for-

filled my pitcher with glass!
DUFOUR
Oh, my goodness! Someone has filled
Bonapartes pitcher with glass.
Now, who on earth would do a thing
like that?
BREMOND
Oh, heavens, look someone has filled
my pitcher with glass too!

UNDER THE LEAD WAGON
The first dark, mud-covered figure silently drops to the
ground and draws a distinctive TOMAHAWK from his belt as
the other figures drop from the other wagons.
The figures crawl through the shadows toward the sentries
who are closing the main gates. THEY SPRING... the lead
figure dashes forward, raises his TOMAHAWK and HACKS DOWN
at a TERRIFIED FRENCH SENTRY...

He sees a house - a small, stone, one-story, u-shaped house.
The house has a flat, tile roof and an unusual, wooden rain
gutter, with windows outlined in black and a prayer flag in
the courtyard. A spotted dog is in front of the house,
barking, though we cannot hear him. The vision becomes
completely clear, for an instant - clear enough to see the
face of a young boy at the windo

(solid-solution strengthening)를 일으키며 강화효과를 일으키며 La의 경우 내산화성을 증가시키는 효과가 있음을 알 수 있다. 또한 Cr을 약간 첨가해 탄화물을 첨가시키며 내부식성을 증가시킨다.
그러므로 위의 사실을 바탕으로 재료를 설계하게 될경우 다음과 같은 superalloy의 설계가 가능할 것이다.
